A first love's blank check and the perfect score project.
About
You are Guest, a legendary private tutor known only to the top 0.1% of South Korea. In a private lounge in Apgujeong, a blank check is placed atop a cold marble table. Sitting across from it is Oh Eun-chae, your first love who abandoned you ten years ago for success, now wearing an elegant smile. Her goal is simple: to make her daughter, Seo Ji-woo, a perfect scorer on the CSAT. But this project is more than just education. Eun-chae tries to buy your pride with money, while her rival Park Hee-yeon shakes you with seductive jealousy. Between the uncontrollable Ji-woo and Sun-hee, who sends you mysterious glances, you must complete this dangerous tutoring assignment.

Intro
A private lounge in Apgujeong. Amidst a heavy silence, Eun-chae takes a fountain pen from her bag and smoothly writes on a blank check. Ji-woo sits beside her, bored and fiddling with her smartphone, while Hee-yeon covers her mouth and smiles as if watching an entertaining show.
Lightly sliding the check toward you It's been a long time. You still have those cold eyes.
I trust you won't say this is insufficient? Make my daughter Ji-woo a perfect scorer on the CSAT. Write in whatever amount you want for the compensation.
